TO THE EDITOR?Avian influenza viruses are occasionally able to cross species barrier to infect humans, and this infection depends on behavioral, environmental, and genetic factors. Previous studies have demonstrated that contact with poultry, especially sick or dead poultry, was the risk factor for infection with avian influenza [1, 2]. Because the general population is much less likely than poultry workers to come into close contact with poultry, the risk of infection with avian influenza is deemed to be insignificant in the general population. Nonetheless, even without poultry-handling practices, residents of general population dwellings in rural areas should not be neglected by investigators, because ?

I wish this paper was open access.

Chinese scientists find evidence of avian flu infection with 2 strains
Chinese researchers identified several villagers who didn't handle poultry to be seropositive for avian flu, including a man who tested seropositive for two strains, according to their letter in Clinical Infectious Diseases yesterday. They conducted a serologic analysis of 605 Beijing-area residents, randomly selected from 24 villages ,who did not have a history of handling poultry. The investigators found antibodies against H9 avian flu by hemagglutination inhibition assay in five of the villagers, and one of these, a 55-year-old man, also tested positive for H5 antibodies. The group also tested for H7 antibodies, with no positive results. The 55-year-old man's son also tested positive for H9 antibodies, but neither his wife nor his daughter-in-law tested seropositive for avian flu. The authors conclude, "Standard surveillance systems for preparedness and response to pandemic influenza, focusing mainly on poultry workers, seem insufficient. Our findings warrant enhanced surveillance of general populations in the future, especially of populations dwelling in rural areas."
